Environmental regulatory requirements of hot water district heating systems in the Minneapolis-St. Paul metropolitan area

Technical Report ·
OSTI ID:6924714

A study was made of the environmental regulatory requirements for implementing district heating/cogeneration in the Minneapolis - St. Paul Twin Cities area. Two district heating scenarios were assumed: (1) a 200 MW(t) hot water system using an existing power plant as a heat source to serve the St. Paul central business district and the Capitol complex area; and (2) a regional 2600 MW(t) hot water system using existing power plants plus one new cogeneration unit to serve a large portion of the Twin Cities metropolitan area. All required environmental permits and authorizations were profiled and a flowchart was prepared to illustrate each process. Timelines were developed showing typical sequences of permitting and construction. The cost of compliance was estimated and overall application strategies were recommended. Suggested modifications to the regulatory process were also developed. 10 references, 40 figures, 1 table.
